What's the best solution for mobile Internet and email?
I have DSL and a wireless router at home, which gives me mobility around the house, and WiFi hotspots, such as when I've been visiting my Mom in the hospital. I know of certain establishments, such as McDonalds, Burger King, Barnes and Noble, and others that have WiFi hotspots but don't really make much use of them.
My sister has an iPhone, which has a web browser and email client,WiFi access if available, and falls back to 3G or Edge networks if not. I don't have much personal experience with it, but she's shown me the features and it looks pretty attractive.
There are coming out new generation netbooks with 3G access as well.
Now my question is, what is the most cost efficient, and effective solution at this time, or in the near future? Each of these solutions has other features as well, such as office and other applications on the netbook, and on the iPhone, a phone, camera, the availability of books, etc.
There is the cost of DSL or Cable to use either one at home, and for the iPhone and next gen 3G netbooks, the monthly costs of 3G access.
Now if someone has a budget constraint, and basically just wants to get online at the lowest possible cost, what would be your recommended solution?

You have mention the DSL issue before, but doesn't the cable company offer high speed internet? (It is good to see you this morning sister.)
